That's not true.  The structure type is also used in arrays and in
other structures, whether on the stack or not.

I think this is, at least, a misunderstanding of Bjarne Stroustrup's
point of view.  Stroustrup sees support for "concrete types" - that is,
classes with value semantics, not intended to be subclassed - as an
important feature of C++.  In the 3rd edition of TC++PL he talks
about them in some detail.
